Reading http://www.techsupportforum.com/forums/f108/solved-laptop-makes-beeping-noise-596567.html it looks like it's the HDD or another bios error.
Hi All -
My boss has a Sony Vaio VPCS111FM laptop we bought from Best Buy last year. It is a Intel i7 processor, Windows 7 with at least 4 GB ram.
Lately when he clicks on anything (file, program, windows explorer, etc) the laptop emits a single "beep" for each click. Each beep lasts no longer than 1 second.
I've tried to search Sony's support & ended up updating his BIOS to the latest version. This seemed to solve the "beep" noise, but now it is back. In speaking with Sony support, all they will suggest is to bring it in for service which will be $129 minimum. They seem to think it is a hardware error, but cannot be certain.
Has anybody else had this happen with your Sony Vaio?
Does anybody have a solution?
